Developers

Reviewed on 5 October 2026
On this page
Developers page with the base address, the authentication, the quota and the API reference.

This is the public reference of the OnBio API and webhooks. Whoever programs an integration with your store reads it, without having to sign in to OnBio. It explains how to authenticate, the request quota, each API route and each webhook event.

How to get there

Open onbio.es/developers, or click Developer reference in Integrations in the panel.

What you can do

  • See the base address, the authentication and the quota.
  • Read the API reference, with the parameters, the responses and an example of each route.
  • Look up the Webhook events and when each one arrives.
  • Copy the Verify the signature example with Copy the code.
  • Open OnBio on Zapier or on Make.

Step by step

Start an integration

  1. 1. Click Create a key to go to your integrations.
  2. 2. Create the key with the permissions you need.
  3. 3. Call the API with the key in the header the page explains.

What happens next

Your software reads your store's sales, contacts, products and invoices. With the write key it also saves contacts with their tags.

Keep in mind

  • The reference is read from the document the API publishes, so it is always up to date.
  • To create a contact through the API you have to confirm it has given consent.
  • If you do not program, use Zapier or Make.
